LOOlVI-SHUTTLE.

Specification of Letters Patent.

Patented June '7, 1921.

Application filed April 27, 1918. Serial No. 231,063.

T 0 all whom it may concern:

Be it known that I, Henson W. HAKES, a citizen of the United States,residing at Millbury, in the county of Worcester and State ofMassachusetts, have invented a new and useful Loom-Shuttle, of which thefollowing is a specification.

This invention relates to a loom shuttle and particularly to bobbinholding devices therein.

In automatic weft replenishing looms it is common to replenish the weftby forcing a fresh bobbin downward into the shuttle, thereby displacingan exhausted bobbin. The bobbins are each provided with a plurality ofrings around their butts, and are held in the shuttle by grooved steelsprings which engage these rings. These springs are subjected to heavyblows and to repeated jars and vibrations.

It is the general object of my present invention to improve theconstruction of devices for holding these springs in position in theshuttle body, so that the spring and all parts associated therewith maybe rigidly secured and retained in position.

With this general object in view, my invention consists in certainarrangements and combinations of parts hereinafter described and morefully pointed out in the appended claim.

A preferred form of my invention is shown in the drawings, in which-Figure 1 is a plan view of a shuttle having my invention embodiedtherein;

ig. 2 is a longitudinal sectional elevation of the parts shown in Fig.1;

Fig. 3 is a transverse sectional elevation taken along the line 3-3 inFig. 2;

Fig. 4 is a plan view of the bobbin-holding spring and spacing block;

Fig. 5 is a side elevation of the parts shown in Fig. 4;

Fig. 6 is a perspective view of the springholding plate, and V Fig. 7 isa perspective view of the spacing2 block.

eferring to the drawings, I have indicated a shuttle 10 and a bobbin 11provided with rings 12 which are held in grooves 13 in a two-armedbobbin-holding spring 14.

This spring is preferably formed from a single piece of flat steel bentto the outline shown in Fig. 4. The grooves 13 are milled in the innerface of each arm and the upper edges of the spring are beveled at 15(Fig. 3) to more readily admit the bobbin.

Preferably this bevel is continuous for the entire length of the springand is formed in the operation of rolling the steel, thus eliminatingthe expense of milling the edges of each spring.

A spacing block 16 is closely fitted between the arms of the spring 14,and the spring and block are perforated for a screw 17 by which they aresecured in the shuttle. A retainer 18 is passed around the spring 14 andis secured at one end to the shuttle 10 by a screw 19. The retainer 18is provided with an inclined portion 20 which assists in guiding thebobbin to its correct position between the arms of the spring 14.

A spring-holding plate 21 is interposed between the upper edge of thespring 14 and the retainer 18. This plate has extensions 22 on bothsides which extend forwardly over the edges of the spring 14 and assistmaterially in securing the spring in position. The body portion of theplate 21 is provided with an opening 23 (Fig. 6) through which extendsthe projecting upper end of the spacing block 16.

With this construction, the parts are all held together in a peculiarlyrigid and immovable condition, and displacement of any part is renderedpractically impossible. In particular, the extension of the spacingblock 16 through the opening in the plate 21 absolutely prevents changein relative position between the plate 21 and the spring 14 which issecured in position by said plate.

Having thus described my invention, it will be evident that changes andmodifications can be made therein by those skilled in the art withoutdeparting from the spirit and scope thereof as set forth in the claim,and I do not wish to be otherwise limited to the details hereindisclosed, but what I claim is- In a loom shuttle, a two-armedbobbinholding spring, a bobbin-guiding retainer inclosing said spring, aspring-holding plate interposed between the upper edge of said springand said retainer, said plate having a body portion and branched sideportions extending forwardly to engage the arms of said spring andhaving an opening through its body portion a separate spacing block heldin fixed position between tne sides of said spring, said block extendingabove said spring and fitting into said opening to po sition said plateand to positively prevent longitudinal or transverse movement of saidplate relative to said block, and means to 10 hold said parts inoperative relation in said shuttle.
